When people are in the room, oxygen is consumed very quickly and carbon dioxide is released.
It is recommended to ventilate from a CO₂ load of 1,000 - 1,500 ppm, as the first effects on the ability to concentrate can already be felt here. Fresh air should be let into the room at 2,500 ppm at the latest, otherwise there is a risk of headaches and tiredness.
The CO2 calculator makes the following assumptions
A person breathes in and out 15 times per minute.
One breath has a volume of 700 ml
The exhaled air has a CO2 concentration of 40,000 ppm
Fresh air has 450 ppm CO₂
The room is airtight and there is no air exchange / no fresh air
We are continuing to work on improving the air-Q carbon dioxide exposure calculator and are open to requests and suggestions for improvement.
